Abstract
A method for degrading, detackifying and reducing solvent in water comprising organic solvent-laden water-borne paint that comprises adding to the water an effective degrading, detackifying and/or solvent-reducing amount of at least one microorganism culture and sufficient micronutrients to sustain the growth of the at least one microorgansim culture and to reduce solvent content of the water. A method of reducing chemical oxygen demand in water comprising organic solvent-laden water-borne paint, wherein the water contains an excess amount of organic solvent from one or both of paint spray operations and paint spray nozzle cleaning operations, the method comprising adding to the water an effective degrading and detackifying amount of at least one microorganism culture and micronutrients to sustain the growth of the at least one microorgansim culture, whereby chemical oxygen demand in the water is reduced by at least 50% relative to the same system without adding the micronutrients.
